CleanSeaNet is the European satellite-based oil spill and vessel detection service which offers assistance to participating States for the following activities:
· Identifying and tracing oil pollution on the sea surface;
· Monitoring accidental pollution during emergencies;
· Contributing to the identification of polluters.
The following products are available in CleanSeaNet
Value added products | Description |
---|---|
Oil spill detection |
The oil spill detection product refers to the identification of potential oil spills in satellite images (both SAR and optical). The nominal delivery times for this product are 20 minutes for SAR based images and 40 minutes for optical. The relevant attributes of the oil spill product are:
|
Vessel detection |
The vessel detection product refers to the extraction of vessel positions based on echoes or detectable objects in the satellite image that may be vessels. This product has nominal delivery times of 20 minutes for SAR-based and 40 minutes for optical-based products and it includes the following attributes:
|
Met-Ocean products (SAR derived wind and wave) |
This product entails the delivery of a package containing ocean surface wind and wave (swell) derived from SAR imagery. The attributes of these products are:
|
Fusion products | Description |
---|---|
Vessel detection correlation |
Vessel detections derived from SAR and optical images are correlated against vessel data, such as:
This product provides an overview of which vessels are reporting and which are not in a given area and contains two layers:
|
Oil spill alert reports |
This product is based on the Quasi Real Time (QRT)/Near Neal Time (NRT) analysis of satellite images in order to detect possible oil spills on the sea surface. When a possible spill is detected within the alert area of a coastal state, an oil spill notification is sent to the relevant authorities. This report includes:
|
Full documentation characterizing the individual data elements for basic, value added and fusion products are available in the Earth Observation Data Centre (EODC) External Interface Control Document (EICD) version 2.0.0.
Directive 2005/35/EC (since amended by Directive 2009/123/EC) on ship-source pollution and on the introduction of penalties, including criminal penalties, for pollution offences. The Directive tasks EMSA to "work with the Member States in developing technical solutions and providing technical assistance in actions such as tracing discharges by satellite monitoring and surveillance".
The CleanSeaNet service is based on the regular ordering of Synthetic Aperture Radar (SAR) satellite images, providing night and day worldwide coverage of maritime areas independent of fog and cloud cover. The information retrieved includes among others: spill location, spill area and length, confidence level of the detection and supporting information on the potential source of the spill (i.e. detection of vessels and oil and gas installations). Optical satellite images can also be acquired upon request, depending on the situation and user’s needs and mostly in support to pollution emergencies
The following sources of data are used in CleanSeaNet products:
Synthetic Aperture Radar (SAR) | Optical |
---|---|
Sentinel-1A/B L1B | Worldview-1/2/3 |
Radarsat-2 | GeoEye |
TerraSAR-X/Tandem-X | Pleiades 1A/1B |
PAZ | SPOT-5/6/7 |
Deimos-2 | |
EROS-B |
The provision of CSN relies on several different technical components:
Public administrations (e.g. marine pollution response authorities, harbour authorities, coast guard) from the 27 EU Member States and EFTA coastal states can access the CleanSeaNet products. Additionally, beneficiary countries of the European Neighbourhood Policy projects can also access the service.
